Slaving and disabling actuators with voice-coil adaptive mirrors
2020Adaptive mirrors based on voice-coil technology have force actuators with an internal metrology to close a local loop for controlling its shape in position. When actuators are requested to be disabled or slaved, control matrices have to be re-computed. The report describes the algorithms to re-compute the relevant matrixes for controlling of the mirror

Construction of a Voice Coil Actuator Array for an Adaptive Optics System
Optical Design and Fabrication 2017 (Freeform, IODC, OFT), 2017We are developing a prototype deformable mirror with engineered ceramic material for adaptive optics in high-power applications. We report preliminary test results from a voice-coil actuator array intended to drive this mirror at kHz rates.

Design and Optimization of a Voice Coil Actuator for Precision Motion Applications
IEEE Transactions on Magnetics, 2015There has been increasing attention to the use of voice coil actuators (VCAs) for precision motion applications. In this paper, a detailed design of a cylindrical VCA is presented. Different options for the overall configuration are evaluated according to various criteria and design variables are defined for the chosen configuration.

Application of voice coil actuator to the measurement of rubber mounts properties
2016 6th IEEE International Conference on Control System, Computing and Engineering (ICCSCE), 2016Rubber mount is the device that commonly used for vibration isolation in many mechanical designs. Many measurement methods are studied for better characterizing the dynamic properties of the rubber mount. This paper focus on the application of the voice coil actuator in the characterization of rubber mounts properties.

High-powered voice coil actuator for fast steering mirror
Optical Engineering, 2011Voice coil actuators (VCAs) are applied in a fast steering mirror (FSM), precision positioning platform, etc. These applications demand that the VCAs used are simple, inexpensive, reliable, and efficient. In this paper, we report a novel VCA with concentration flux-line structure.

Design of a voice coil actuated office chair
2005In recent times, the use of robots in industry has revolutionized production methods, and enabled an increase in the quality of goods manufactured while decreasing the long term cost of labor. The commercial market, however, is largely lacking in robotic technology which could potentially revolutionize many everyday tasks undertaken by humans.

Acceleration feedback design for voice coil actuated direct drive
Proceedings of the 1999 American Control Conference (Cat. No. 99CH36251), 1999Development of a servo-control system for a voice coil actuated direct drive used in turning of automotive camshafts is presented. The drive must possess low inertia, in order to satisfy motion bandwidth requirements for cam turning with a small actuator.
